After that functions which add matches, show_journal_by_unit
and show_journal_by_user_unit, become nearly identical, so
I merged them into one function.
|
|
I can't find a reason why we shouldn't try to output messages for other
unit types than .service, .socket, .mount and .swap as well. It's probably
a leftover from before we started logging UNIT= from inside PID 1.

Print the journal for a user session unit. For now this filters by
_SYSTEMD_USER_UNIT and USER_UNIT and additionally _UID.

This introduces a new data threshold setting for sd_journal objects
which controls the maximum size of objects to decompress. This is
relieves the library from having to decompress full data objects even
if a client program is only interested in the initial part of them.
This speeds up "systemd-coredumpctl" drastically when invoked without
parameters.

The message catalog can be used to attach short help texts to log lines,
keyed by their MESSAGE_ID= fields. This is useful to help the
administrator understand the context and cause of a message, find
possible solutions and find further related documentation.
Since this is keyed off MESSAGE_ID= this will only work for native
journal messages.
The message catalog supports i18n, and is useful to augment english
language system messages with explanations in the local language.
This commit only includes short explanatory messages for a few example
message IDs, we'll add more complete documentation for the relevant
systemd messages later on.

This now matches the JSON serialization spec from:
http://www.freedesktop.org/wiki/Software/systemd/json

|
|

text/event-stream
|
|
Among other cleanups this introduces a threshold for the size of binary
blobs we serialize as integer arrays in the JSON output. THis can be
disabled via --all.

This splits the JSON output mode into different modes: json and
json-pretty. The former printing one entry per line, the latter showing
JSON objects nicely indented and in multiple lines to make it easier to
read for humans.
|
|
journalctl -f redirected to a pipe or file wasn't working for some
output formats but was working for json. It turns out only json was
doing an fflush.
Make all output formats flush.

Ellipsize lines that are one character too long.

warn/notice = bright white
< error = red

also a number of minor fixups and bug fixes: spelling, oom errors
that didn't print errors, not properly forwarding error codes,
few more consistency issues, et cetera

glibc/glib both use "out of memory" consistantly so maybe we should
consider that instead of this.
Eliminates one string out of a number of binaries. Also fixes extra newline
in udev/scsi_id

When showing the journal through "journalctl --no-pager", if the
prefix of the log message (i.e. the date and syslog identifier) is
less than 3 characters shorter than the width of the terminal, you
get:
Assertion 'new_length >= 3' failed at src/shared/util.c:3859, function ellipsize_mem(). Aborting.
because there is not enough space for the "...". This patch add the
necessary check.
|
|
If a pager is used, ellipsization is redundant — the pager does
that better by hiding the part that cannot be shown. Pager's advantage
is that the user can press → to view the hidden part of a message,
and then ← to return.

Convert more flag arguments into one flag variable.
|
|
In preparation for adding more output switches, convert a series of
flags arguments into one flag variable.
|

|
This makes sure we are OK in outputting all valid, non-control UTF-8
characters, instead of just printable 7bit ASCII.
|
|
|
|
This helps explaining when the log output of "systemctl status" is
incomplete because the logs got rotated since the service was started.
